নির্দেশনা
Aflibercept, in combination with 5-fluorouracil, leucovorin, irinotecan-(FOLFIRI), is indicated for patients with metastatic colorectal cancer (mCRC) that is resistant to or has progressed following an oxaliplatin-containing regimen.
Composition
ফার্মাকোলজি
Ablibercept is a recombinant fusion protein that acts as a decoy receptor for the ligands, vascular endothelial growth factor-A (VEGF-A) and placental growth factor (PIGF). It prevents these ligands to binding to endothelial receptors, VEGFR-1 and VEGFR-2, to suppress neovascularization and decrease vascular permeability. This ultimately will slow vision loss or the progression of metastatic colorectal cancer.

Pregnancy category C. There are no adequate and well-controlled studies with Aflibercept in pregnant women. Aflibercept was embryotoxic and teratogenic in rabbits at exposure levels lower than human exposures at the recommended dose, with increased incidences of external, visceral, and skeletal fetal malformations. Aflibercept should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether Aflibercept is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for serious adverse reactions in nursing infants from Aflibercept, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
সতর্কতা
Adverse reactions, sometimes severe and life-threatening or fatal, have been seen in clinical trials with Aflibercept, including: Fistula Formation: Discontinue Aflibercept if fistula occurs. Hypertension: Monitor blood pressure and treat hypertension. Temporarily suspend Aflibercept if hypertension is not controlled. Discontinue Aflibercept if hypertensive crisis develops. Arterial Thromboembolic Events (ATE) (e.g., transient ischemic attacks, cerebrovascular accident, angina pectoris): Discontinue Aflibercept if ATE develops. Proteinuria: Monitor urine protein. Suspend Aflibercept when proteinuria ≥ 2 grams per 24 hours. Discontinue Aflibercept if nephrotic syndrome or thrombotic microangiopathy (TMA) develops. Neutropenia and Neutropenic Complications: Delay administration of Aflibercept/FOLFIRI until neutrophil count is ≥ 1.5 × 109/L. Diarrhea and Dehydration: Incidence of severe diarrhea and dehydration is increased. Monitor elderly patients more closely. Reversible Posterior Leukoencephalopathy Syndrome (RPLS): Discontinue Aflibercept.
